Sometimes, it may be needed to test the WPS qualification by performing tests on weld vouchers (test items). Confirming the base steel and welding consumables compliance with the relevant requirements. Examining for joint tidiness and correct fit-up. Making certain that the joint design and weld prep work is certified with the WPS and applicable welding requirements (ASME, AWS, API).




In some cases, pre-welding assessment might locate irregularities that are within code restrictions however can pose a problem at a later phase in manufacturing. That's why it's important for the welding assessor to be familiar with the whole manufacturing procedure and to be experienced with the bonded devices.
